Model GG1H-72 | Mono PERC+ Bifacial | 72 Full-Cell Monocrystalline | Bifacial | 1500V System Voltage
The GTC GG1H-72 450W Mono PERC+ Bifacial Dual Glass Solar Panel delivers high power density for commercial and residential projects seeking dependable energy yields. This advanced bifacial module uses efficient monocrystalline PERC cells and dual glass construction to maximize electricity production and long term durability in demanding climates. With front side power up to 450 watts and a bifacial boost of up to thirty percent, systems can achieve greater output from the same footprint. The focus keyword GTC Trade 450W is associated with reliable performance, robust engineering, and optimized levelized cost of energy across the full operating life. Designed and manufactured in Turkey by GTC Güneş Sanayi ve Ticaret A.Ş., this module is ideal for rooftops, carports, ground mounts, floating arrays, trackers, and architectural integrations. The low degradation rate and extended warranties support bankable projects and long term investment confidence.
High power density for compact arrays: Up to 450 watt front side output allows more installed capacity on limited roof or land area. System designers can reduce the number of modules while maintaining target production levels.
Bifacial boost for lower energy costs: The bifacial design harvests additional energy from the rear side using ground reflection and diffuse light. Depending on surface albedo, power gains up to thirty percent can be realized, helping to reduce levelized cost of energy.
Engineered for hot and harsh climates: Optimized temperature coefficients and excellent low light response support stable production in high heat and variable weather. The dual glass structure and 6X durability technology are tested beyond standard IEC requirements for long service life.
Long term reliability and low degradation: The panel features a low annual degradation rate of around zero point five three percent. Power output is warranted at ninety five percent after ten years and eighty four percent after thirty years, supporting predictable project cash flows.
Flexible application and clean aesthetics: The glass glass portable frame design enables use on carports, rooftops, floating structures, sun breakers, and trackers. The bifacial dual glass construction provides a modern appearance, with transparent options available on request for architectural projects.
Reduced operations and maintenance effort: The portable frame and smooth glass surfaces minimize dust and snow accumulation. Better self cleaning characteristics help maintain power levels while reducing manual cleaning frequency and associated costs over time.
The GTC GG1H-72 450W Mono PERC+ Bifacial Dual Glass Solar Panel converts sunlight into direct current electricity through high efficiency monocrystalline PERC cells arranged in a seventy two cell layout. Light striking the front glass is absorbed in the silicon cells, where photons release electrons and create a flow of current. The bifacial architecture simultaneously captures light on the rear side, including ground reflections and scattered light from the environment, which enhances total energy yield without increasing the module footprint. Both sides are protected by durable tempered glass, which seals the encapsulated EVA and cells against moisture and mechanical stress. The generated direct current is carried through the junction box and MC type connectors to inverters or charge controllers, where it is converted into usable alternating current power. Optimized temperature coefficients support efficient operation in hot conditions, while the robust double glass structure ensures reliable performance over several decades of service.
Front side monocrystalline PERC generation: The front side uses high quality monocrystalline PERC cells operating at a maximum power of 450 watt under standard test conditions. Each cell is designed to minimize resistive losses and capture more light, which increases efficiency up to twenty point seven one percent. Under standard one thousand watt per square meter irradiance and twenty five degree cell temperature, the module delivers a maximum power voltage of about forty one point nine five volt and a maximum power current of around ten point seven five ampere.
Bifacial rear side energy capture: The rear side cells are exposed through the transparent glass back, enabling energy harvest from reflected and diffuse light. When installed above bright surfaces such as concrete, light colored gravel, or reflective membranes, the albedo effect can provide up to thirty percent additional output. This bifacial gain increases total system production without requiring extra modules, which helps to optimize layout on ground mounts, trackers, and carports.
Dual glass encapsulation and durability: Both the front and rear of the module use tempered glass with anti reflection coating to protect the cells while allowing high light transmission. The encapsulant material, based on EVA, secures the cell strings and prevents delamination, moisture ingress, and mechanical damage. The double glass portable frame design supports up to fifty years of service time in real world installations, with enhanced resistance against salt mist, humidity, and thermal cycling beyond standard IEC test levels.
Electrical interface and system integration: The integrated junction box uses three bypass diodes to reduce power loss under partial shading and maintain stable string performance. MC type connectors provide a secure, industry standard interface to string wiring and inverters. With a maximum system voltage of fifteen hundred volt and a series fuse rating of twenty ampere, the module supports long strings, reduced cabling, and efficient array design on utility and commercial systems.
